As the title suggests.

Can anyone see anything I can't?Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is
-
what means you can't tune it ? is there a error message ? what happens after M303 H1 S240 (for example)
-
If I type M303 H1 S210 all I get is a green box with a tick
I have also powered down and up again to make sure the config has been loaded on the duet 3HC -
@jay_s_uk Tuning remote heaters is one of the things that is still unsupported. About the only thing we can do right now is make up extension leads and temporarily connect the heater and thermistor to the main board in order to run heater tuning.

That'll be why it doesn't work then.
Thanks @deckingman -

Thanks @deckingmanFor info, the other things that I'm aware of that are "pending" with expansion boards is M581 triggers and hiccups reported by M122. Also Z probes are not yet supported (as opposed to switches). You may also find that any thermostatic fan connected to an expansion board will randomly "blip" when the machine is idle.
